Opening less than a week after the second season of the Galileo television drama concluded, the crime procedural — starring popular actor FUKUYAMA Masaharu 福山雅治 as a genius physicist who investigates a murder case in a seaside town — made ¥468 million (US$4.69 million) in two days.

On Saturday afternoon, distributor Toho Co Ltd 東宝 announced that Midsummer's opening day admissions were on track to eclipse the first movie by 115%. It predicted that Midsummer would cross the ¥5 billion mark in Japan, which would position it as the highest grossing domestic live-action film of the year.

Opening day-and-date in Hong Kong on Saturday, Midsummer made HK$1.48 million (US$192,000) in its first two days, despite opening against Man of Steel (2013). Distributor Panasia Films Ltd 泛亞影業有限公司 told Film Business Asia that Fukuyama's Hong Kong visit played a major role in raising awareness for the film.
